RADIATOR FOR MOTOR CARS AND THE LIKE.

Application filed October 5, 1920. Seria1 No; 414,887.

To all w hom it may 0071 cam: I

Be it known that I, ALEXANDRELAMBLIN, subject of the King of Belgium,residing at Paris, France, have invented certain new and usefulImprovements in Radiators for Motor Cars and the like, of which thefollowing is a specification.

The present invention relates to sundry improvements in coolingradiators for thermal motors. Radiators constructed according to myinvention comprise cooling elements such as flat tubes in which thecooling water circulates, these tubes being fixed at three points neartheir base to three conduits for the inflow and outflow of the water,and means for securely connecting the cooling elements with the waterconduits.

This arrangement permits the flat tubes to expand freely under theaction of heat when the motor is started.

Several form of the invention are illustratively exemplified in theaccompanying drawings in which Fig. 1 is an elevational view of aradiator with certain of the cooling elements omitted; Fig. 2 is ahorizontal section on the line a-b of Fig. 1; Fig. 3 is a substantiallycentral vertical section through Fig. 1; Figs. at and 5 are respectivelya side elevation and a front elevation of. a modified form of radiator;Figs. 6 and 7 are views similar respectively to Figs. 4 and 5 of a stillfurther modified form; Figs. 8 and 9 are respectively a front elevationand a plan view of another modified form of radiator embodying theinvention.

1. The cooling radiator shown in Figs. 1, 2 and 3, comprises a reservoirA provided with a filling cap B, and is placed in communication with thetop of the engine by a tubular socket C.

The hot water arriving from the engine by the tube C flows into the twolateral tubes D through the apertures E, and into the collectors Fthrough the apertures G extending through the entire height of theradiator. The water is conducted through the cooling elements H thusbeing cooled. The water then returns to the engine through the tube Iand the outlet K.

Thus is effected a distribution of hot water throughout the entireheight of the radiator by the tubes D. The section of orifice G beingsmaller than that of the orifice by which the fiat tube H communicateswith the collector F, it follows that it is possible to regulate asdesired the radiator flow by giving the orifice G a desired sectionalform in the course of construction.

The elements of the radiator H are spaced by the tubes L, which maintainthem suitably separated for leaving a very freepassagefor thecirculation of the air.

The members H are secured to the collectors F and to the cold watercolumn I by three soldered joints, which are the sole means ofattachment, to which easy access is had either by a soldering iron, orby a blowpipe to fix them or to detach them in order to replace them.

The group thus formed is secured in a removable automobile front orframe of the construction disclosed in my Patent Number 1,403,967 issuedto me January 17, 1922, such frame being carried by the chassis of thevehicle. The base of the group rests on the base of the frame and isconnected thereto by the bolts M. The flange N of the radiator capengages a corresponding flange of the frame and these two flanges may besecured together by bolts. From this can be observed the facility withwhich it is possible to withdraw the radiator from its frame tr effectthe repair or the replacement there- 0 2. Figs. at to 7 represent, byway of ex ample, two other embodiments on the same principles, similarto. the former, but in these examples the hot water arrives by a centralvertical cylinder D and returns to the engine after cooling by twolateral vertical cylinders.

These two embodiments differ from one another only by the shape of thecooling surfaces, which are cylindrical and upwardly convened in thefirst form (Figs. 4 and 5) while they are mansard shaped in the secondform (Figs. 6 and 7). Figs. 8 and 9 show an embodiment 0n the foregoingprinciples which differ from the embodiment of Figs. 1 to 3 only by theshape of the cooling surfaces.

3. The contrivances as shown in Figs. 1 to 9 are applicable to all kindsof radiators, but more especially to radiators of, automobiles, whereinthe fiow of the air is facilitated by the displacement of the radiator.

In allforms of the invention the construction is one assuring freeexpansion of the cooling elements, simplicity of construe tion andmounting, and finally ease and rapidity of repair. Moreover by reason ofthe construction if any one of the elements is omitted or out ofoperation the radiator will function satisfactorily with the remainingelements.
